Update assetgraph to 1.6.35 and remove the logEvents transform (assetgraph/assetgraph#194).
findUntranslatedHtml: Added 'unselectable' to the list of ignored attributes.
Tests: Removed this.timeout calls now that mocha.opts specifies a long timeout.
Tests: Use the unexpected-jsdom plugin.
Html: Introduce a syntax for pieces of text that explicitly should not be translated.

    <div data-i18n="">Do not translate me</div>
    <div data-i18n="text: null">Do not translate me</div>
    <div data-i18n="attr: {title: null}" title="Do not translate me"></div>
Merge the findUntranslatedHtml script into the checkLanguageKeys transform.
checkLanguageKeys: Ignore obscure tags found in Htc files when looking for untranslated text in html.
